[This review was collected as part of a promotion.] ZzzQuil's Nighttime Sleep-Aid did not provide me with any sleep aid. I had a few sleepless nights so I thought I would try this but it had no effect on my sleep at all.

[This review was collected as part of a promotion.] This product did not work for me however I have a high tolerance to medication so it may work for some.

[This review was collected as part of a promotion.] No Z for me either the ZzzQuil Nighttime Sleep-aid. It might have relaxed me a little but didn't put me to sleep.

[This review was collected as part of a promotion.] I tried the zzzquill nighttime sleep aid and it really didn't help me sleep. I think if I had several nights of the sample I could make a better review.

[This review was collected as part of a promotion.] ZzzQuil nighttime sleepaid didn't really do much for me. I have a really hard time sleeping at night but taking this didn't really help much

[This review was collected as part of a promotion.] I guess I just felt like this product would actually make a difference. It definitely didn't. Maybe it just doesn't work for me.

[This review was collected as part of a promotion.] There is no use in taking zzzquil Nighttime sleep aid. I have received multiple free samples and it does not affect or help me sleep!

[This review was collected as part of a promotion.] ZzzQuil Nighttime Sleep-Aid just didn't live up to expectations. It was almost like taking a sugar pill

[This review was collected as part of a promotion.] I tried this sample and it gave me the much needed deep sleep my body was in need of. It didn't give me the groggy feeling like I had with NyQuil.

[This review was collected as part of a promotion.] I only use ZzzQuil Nighttime SleepAid On nights I drank too much caffine. It helps get me to sleep fast and I don't wake up groggy. I do have some vivid, intense dreams though.
